The quoting around the expansion of ${relative_dir} was indeed incorrect
since it was introduced back in 8fe9894f65 (suport/download: fix git
wrapper with submodules on older git versions): it is in fact already
quoted as part of the whole sed expression.
${GIT} can contain more than one item, but we don't care about splitting
on spaces when we just print it for debug, so we can just quote it
rather than add an exception.
